The original members of Black Sabbath-Ozzy Osbourne, guitarist Tony Iommi, bassist Geezer Butler and drummer Bill Ward-came of age during the "Age of Aquarius." You don't hear a lot of Summer of Love as an influence on their music because they didn't experience it in their hometown of Birmingham, England, which was a hard, bleak and industrial city. The music that they were playing, even in the early days when they were known as Earth, was considerably darker than most of the "peace and love" sentiment prevalent during the era.

As such, it should be no surprise that the band found their name during a rehearsal held near a theater showing a horror film. Osbourne recalled, "One day, Tony says, 'Don't you think it's strange that people pay money to go and get scared to death at horror movies?'"

It was a question that resonated with them and so band decided to bring horror to their music. "In our original format, we were a jazz/blues band," Osbourne said, referring to an early incarnation of the group called the Polka Tulk Blues Band. When they took that music and made it a bit more demonic, as Osbourne says, "It just clicked."

Indeed, some might argue that the music we now know as "heavy metal" was born, or spawned, in that rehearsal space with a little thanks to the influence of 1970s horror flicks.
